Abstract

The time-resolved detection of surface plasmon polaritons has been carried out with a scanning tunneling microscope (STM). The results indicate that the time-resolved signal is due to rectification of coherently superimposed plasmon voltages. The comparison with differential reflectivity measurements shows that the tip itself influences the decay of the plasmon-field coherence. Generation of the measured signal at the tunneling junction offers the possibility to observe ultrafast effects with a spatial resolution determined by the tunneling junction.
